Oscillators

BJ-77.760MBE-T application field and working principle

Oscillators are electronic circuits that generate a certain type of signal, usually in the form of a sine wave or a square wave. Oscillators play a very important role in many types of electronic systems, from consumer electronics to scientific instrumentation. BJ-77.760MBE-T oscillator is one of the most common and frequently used oscillators. It is also known as an independent quartz crystal oscillator. BJ-77.760MBE-T oscillators are mainly used in communication devices, including cellular phones, PDA’s, Wi-Fi networks, radio receivers, and other related technologies, in order to transmit signals with a precise and stable frequency. They can also be used in medical and industrial applications, such as ultrasound imaging systems and motion controllers.The working principle of BJ-77.760MBE-T oscillator is based on piezoelectric effect. The oscillator contains a quartz crystal, placed between two metal electrodes. When a voltage is applied to the crystal, it produces mechanical vibrations which generate a high-frequency sine-wave. The crystal is designed to have a resonance frequency, and it will vibrate at this frequency when a voltage is applied. This frequency-controlled oscillation is called a free-running oscillator. The BJ-77.760MBE-T oscillator also uses a coupling capacitor to couple the output signal and the power supply, and a parallel resistor to protect the quartz crystal from excessive current. The unit is then enclosed in a hermetically sealed metal case and connected to a ground terminal.BJ-77.760MBE-T oscillators are known for their low phase noise, excellent temperature stability, and high frequency accuracy. They offer high reliability and long-term stability, making them ideal for applications where precise and accurate signals are required. The combination of piezoelectric effect and the quartz crystal make the BJ-77.760MBE-T oscillator an excellent choice for many applications that require high accuracy and long-term stability.
